Design of MOS-translinear multiplier/dividers in analog VLSI
López Martín, Antonio
; Carlosena García, Alfonso (Hindawi Publishing Corporation, 2000)
Artículo / Artikulua 
A general framework for designing current-mode CMOS analog multiplier/divider circuits based on the cascade connection of a geometric-mean circuit and a squarer/ divider is presented. It is shown how both building blocks ... -
Effect of the glottal source and the vocal tract on the partials amplitude of vibrato in male voices
Arroabarren Alemán, Ixone; Carlosena García, Alfonso (Acoustical Society of America, 2006)
Artículo / Artikulua
In this paper the production of vocal vibrato is investigated. The most relevant features of the acoustical vibrato signal, frequency and amplitude variations of the partials, will be related to the voice production ... -
Performance comparison and design guidelines for Type II and Type III PLLs
Ugarte Gil, Mikel; Carlosena García, Alfonso (Birkhauser, 2015)
Artículo / Artikulua
The advantages provided by Type III PLLs are poorly known, since these devices are very often considered unstable and difficult, or even impossible, to design. In this paper, a performance comparison between Type II and ... -
Signal processing in ocean bottom seismographs for refraction seismology
Rodríguez Barbarin, Iban; Mànuel Lázaro, Antonio; Carlosena García, Alfonso ; Bermúdez, Antoni; Río, Joaquín del; Panahi, Shahram Shariat (IEEE, 2006)
Artículo / Artikulua
This paper presents some experimental results on the application of signal processing techniques to underwater seismic signals. The novelty of this paper stems from the fact that it is the first paper, to the best of the ... -
Vibrato in singing voice: the link between source-filter and sinusoidal models
Carlosena García, Alfonso ; Arroabarren Alemán, Ixone (Springer Open, 2004)
Artículo / Artikulua
The application of inverse filtering techniques for high-quality singing voice analysis/synthesis is discussed. In the context of source-filter models, inverse filtering provides a noninvasive method to extract the voice ...
